Structural improvement for ice skate blade

ABSTRACT

This invention is a structural improvement for an ice skate blade, where the blade holder and the blade are separate. The blade is made from a hard, wear-resistant material. The upper surface is a relatively thinner connecting surface by a roller shape forming machine. On the surface of the blade, there are several equidistant apertures. A special mold is utilized for mounting the connecting surface of the blade to the blade holder using lighter material materials, namely plastic steel. Thus, the weight reduction of the whole ice skate blade effectively improves the skaters&#39; technique and performance and enhances market competitiveness as well.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a structural improvement for ice skateblade. The upper area of the blade is rolled to be a relatively thinnerconnecting surface, and there are several equidistant arranged apertureson it. The skate blade holder directly takes shape on the connectingsurface of the blade and mounts each other by a special mold.

2. Description of the Related Art

The main defects in producing the previous skate blade and holders havebeen due to the following:

-   (1) Monolithically. Since the blade holder is made from steel, its    weight reduces the skater's performance. As well, the high cost of    the product lessens the market competitiveness.-   (2) Separately. The separate blade holder and the blade have been    assembled using adhesive glue that may be destroyed by the heat    produced by friction while skating. Also, the screws used as a means    to mount the blade to the holders, could easily slipped apart while    skating, which brings about a safety issue. Therefore, the process    of producing blades and holders has problems and safety concerns    whether adhesive glue or screws were used as a fastening means.

As for the previous design as shown in FIG. 1, there is a structuraladvanced invention which belongs to U.S. Pat. No. 5,769,434. There arestill some defects thereof, described as following:

Firstly, the extruded flange and cross through space (40) on the uppersurface of the blade (4) can't be made by monolithic molding; thus makesthe procedure more complicated as it not only decreases the efficiencyand market competitiveness, but also increases the cost of the product.

Secondly, due to the blade being so thin, the edge of the blade (41)can't receive any polishing after a period of time, as t may reduce thedurability of the blade.

Thirdly, the cross through space (40) can't be entirely covered with thepotting material. The combination is incomplete and the degree of dangeris enhanced.

SUMMARY OF THE INVENTION

The present invention is a structural improvement for an ice skate bladewhere the blade holder and the blade are separate. There are severalcharacteristics involved. Firstly, the connecting surface is made to bethinner by a roller shape forming machine. Then there are severalequidistant apertures on it. Finally, a special mold is utilized formounting the connecting surface of the blade to the blade holder.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 2, 3, 4, the ice skate blade (1) is composed of theskate holder (2) and the blade (3). The characteristic of this inventionis that the upper surface of the blade (3) is rolled to be relativelythinner connecting surface (30) by a roller shape forming machine. Addedto this are several equidistant apertures (31) on the surface. The blade(3) which is made form hard and wear-resistant material directly takesshapes on the blade holder. This is made from plastic steel or arelatively light and wear-resistant material. It is then molded in orderto mount the skate blade holder (2) to the blade (3).

Referring to FIG. 5, there is another example of the present invention.The upper area of the blade is rolled to produce a relatively thinnerconnecting surface (30). Then there are several equidistant trianglefillisters on it. The triangle fillisters (5) can be completely coveredwith material potted into the skate blade holder (2).

According to the present invention, the advantages of using the iceskate blade (1) are as follows:

Firstly, the relatively thinner connecting surface (30) can bemanufactured by monolithic molding in order to save time and decreasethe cost of the product. This in turn will enhance efficiency and marketcompetitiveness.

Secondly, the equidistant apertures (31) or triangle fillisters (5) ofanother example enable the potting material to spread completely intothe ice skate blade holder making it a stronger structure and a saferproduct.

Thirdly, the product is more durable due to newly suited thickness ofthe blade (3) and edge of the blade (32). This will allow the blade tobe polished with minimal damaging effect after a long period of time.

Finally, the ice skate holder (2) is made from plastic steel or arelatively light material which is wear-resistant and not easily bentout of shape. Thus, the weight reduction of the whole ice skate bladeeffectively improves the skaters' technique and performance.

1. A structural improvement for the ice skate blade, where the stakeblade holder and the blade are separate. The characteristic of thismechanism is that the upper area of the blade is rolled to create arelatively thinner connecting surface. On this surface are equidistantapertures. The skate blade holder is situated on the connecting surfaceof the blade and they are connected by a special mold.
 2. A structuralimprovement for the ice skate blade in accordance with claim 1, theblade is made from hard and wear-resistant material.
 3. A structuralimprovement for the ice skate blade in accordance with claim 1, theskate blade holder is made form plastic steel or a relatively lightmaterial which is not easily bent out of shape.
 4. A structuralimprovement for the ice skate blade of another example. There areseveral equidistant triangle fillisters on the connecting surface of theblade.
